WHEEL-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 238,944, dated March15, 1881.

Application filed January 22, 1881. (Model.)

To all whom it may concern:

Be it known that I, FRANK B. MANLY, a citizen of the United States,resident at Malta, in the county of Morgan and State of Ohio,

5 have invented certain new and useful Improvements in Wheel-Oultivatorsand I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification, in which-Figurelis aside view, partly in section. Fig. 2 is a top View. Figs. 3,4c, and 5 are sectional details.

This invention relates to wheel-cultivators.

The invention consists in the construction hereinafter described, andparticularly pointed out in the claims.

In the drawings hereto annexed, A is the cultivator-frame, on the arms aof which, between cuffs zy, are sleeved the boxes B. These boxes havedepending sides 0 O,with inwardly-turned flanges c c, forming a slot,1), there being at the mid-length of these flanges the opposite notches,a: as.

D D are screw-bolts, having heads d, adapted to fit notches 00 00,through which said heads are slipped, and the bolts are moved along slotb, the heads fitting snugly the interior of the boxes.

E E are plates, having offsets 6, one at one 5 corner, the other nearthe middle of the side upon which the former is located. These offsetsare perforated at w, and have a lug, c, on each side of thisperforation, said lugs fitting slot b. Along theother edge of the plateE are two slots, 02, with a bridge, 19, between, or the bridge may beomitted.

On the face of the plate, with lugs 71 at the back of slots nfis alongitudinal rib, F, and on the other face of the plate there is a bead,G, surrounding slots n, and forming a seat, 9. This plate is held to boxB by bolts D D passing through perforations w w, lugs 11 resting in slotb,,the plate being adjustable lengthwise on the box.

' I are theplow-beams, secured in front to the yoke K, the latter havingvertically-diverging arms k k, provided at the ends on the inside withseats t t. Seated in these seats tt is the post L, having the stop-pin Zis a swivelplate, having an eye, m, rounded at the rear, and having atthe middle of the curve a groove, 8, said eye also having a smallercurve, r, in front and rabbets g on each end of this curve, the rear ofthe eye being smaller than the front, forming shoulders I.

N is a bearing-block, having a concave face, to, fitting post L, and aconvex back, 1), fitting the rear of eye m, provided with a rib, o,suited to groove 8, this rib having a series of holes, h. n is a groovein this block for stoppin 1 P is a set-screw to pass through a hole, 10in the rear of eye m.

Q is a bolt passing through post L.

The forward part of plate M is a lip, a, having therethrough the hole b,the seat 0 underneath, with groove (1 and shoulder c, the groove fittingrib F on plate E.

R is a bolt for holding plate M to plate E.

Post L, with bearing-block N at the rear, is slipped into eye m, theplate M being held at any point by screw P. The post is then placed inthe seats t t and all held by bolt Q. The plate is made fast at thefront to plate E by bolt R passing through slot n and hole 1), its headresting in seat g, the bolt being held by a not on top. By this meansthe plate M is lengthwise adjustable on plate E.

The object of the construction described is to form a device whichprovides a very nice degree of lateral adjustment to plows, at the sametime giving a large range of movement. The adjustment of plates E onboxes B, of plates M on plates E, and the swiveling of the plow-beams onthe post L, easily and readily permits the accomplishment of thisobject.

What I claim is- 1. Swivel-plate M, having groove d, hole 12, andshoulder e, in combination with plate E, having rib F and slot 11., andbolt R, substantially as described.

2. Box B, having flanges 0 o and slot b, in

combination with bolts D D and plate E, hav- P, substantially as and forthe purposes set ing lugs 'v and holes w, substantially as deforth. IOscribed. In testimony whereof I affix my signature in 3.
